Product Overview: The 1308 Self-Aligning Ball Bearing
The 1308 bearing is a robust component from our 1300 Series of Self-Aligning Ball Bearings, engineered with principal dimensions of 40x90x23mm. Its primary design function is to accommodate significant angular misalignment between the shaft and housing, which can occur from mounting errors or shaft deflection during operation. The bearing features a dual-row ball design and a common sphered raceway in the outer ring, allowing it to self-align and operate smoothly even when alignment is not perfect. This capability makes it indispensable in a wide range of industrial applications, ensuring reduced friction, lower operating temperatures, and extended machine life.
Key Features of the 1308 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment, reducing stress on the shaft and extending the lifespan of machine components.
- Double Row Design: Two rows of balls provide a higher radial load capacity compared to single-row bearings of similar size.
- Cylindrical Bore: Designed for a straightforward press fit onto a standard cylindrical shaft.
- Robust Construction: Manufactured from high-grade bearing steel for superior durability, hardness, and wear resistance.
- Low Friction: The internal geometry is optimized to minimize rotational friction, leading to greater operational efficiency and less heat generation.
- Versatile Performance: Suitable for applications with moderate radial loads and relatively low axial loads in either direction.
Common Applications
- Agricultural Machinery: Widely used in harvesters, seeders, and tractors where rugged conditions and shaft flexing are common.
- Conveyor Systems: Ideal for long conveyor belts where maintaining perfect shaft alignment across the entire system is challenging.
- Fans and Blowers: Accommodates potential shaft deflections caused by imbalances, ensuring quieter and more reliable operation.
- Textile and Printing Machinery: Provides stable support for rollers and shafts, maintaining precision despite slight misalignments.
- Mining and Construction Equipment: Essential in machinery that operates on uneven terrain, where frame distortion can misalign shafts.
- Pumps and Gearboxes: Ensures reliable rotation for shafts that may experience deflection under heavy operational loads.
Benefits of Using the 1308 Bearing
- Increased Machine Uptime: By tolerating misalignment, the 1308 bearing reduces the likelihood of premature failure, leading to fewer breakdowns.
- Extended Service Life: The self-aligning feature minimizes edge stresses and wear, significantly prolonging the bearing's operational life.
- Reduced Maintenance Requirements: Its resilience to misalignment means less frequent need for adjustments, repairs, and replacements.
- Simplified Installation: The ability to self-align makes the mounting process easier and more forgiving of minor installation inaccuracies.
- Improved Performance: Low-friction operation contributes to smoother machinery performance and potential energy savings.
- Reliability in Demanding Environments: Performs consistently in applications where shaft deflection and alignment issues are unavoidable.
